  Title: Feasibility of a Walking School Bus
   Program to Prevent Obesity in Hispanic
   Elementary School Children. C Conklin, N
   Burks, C Roldan, AS Kong. University of New
   Mexico HSC, Albuquerque, NM.
         Sample Abstract
 Purpose: Hispanic children have a high
  prevalence (42.8%) of being overweight or obese
  in the US. The purpose of this study was to
  assess the feasibility of a 10 week trial of the
  Walking School Bus (WSB) Program among a
  population of Hispanic elementary school
  students as a strategy to prevent obesity.
         Sample Abstract
 Methods: Kindergarten through 5th grade
 students who lived within a one mile radius of the
 participating school were recruited. Children
 walked on designated routes to and from school
 supervised by parent volunteers. Four health
 themes were emphasized: (1) get up and play,
 (2) turn off your television, (3) eat five servings of
 fruit and vegetables per day, and (4) reduce soda
 and juice intake. Pre/post questions taken from
 CDC 2005 Youth Risk Behavior Survey, 24-hour
 diet recalls, and height and weight
 measurements were performed to assess health
           Sample Abstract
 Results: Among the 28 children who initially enrolled,
  three dropped out. Remaining 25 were Hispanic with
  56% reporting that Spanish was the preferred language
  at home, ages were 5-11 years, and 64% were female.
  Seventy-six percent of participants walked an average of
  three or more times per week. BMI percentile remained
  fairly stable from 50.8% pre-WSB to 49.3% post-WSB
  (p=0.1). According to pre/post surveys, participants
  increased physical activity from a mean of 4.3 to 5.3
  days/week (p=0.08) and increased their consumption of
  fruit from 0.83 to 1.59 servings/day (p=0.01). Vegetable
  intake more than doubled according to 24-hour diet
  recalls (p<0.001). There were no significant changes in
  television viewing time and soda/juice intake.
         Sample Abstract
 Conclusion: The Walking School Bus program
  was feasible with no excessive weight gain in the
  group of children and self-reported obesity
  reduction behavior changes. The Walking School
 Bus with health themes may be an important
 childhood obesity prevention strategy from a
 public health promotion perspective.

 The Walking School Bus (WSB) began in 1992
  in Brisbane, Australia and promotes safe, active
  commuting to and from school for students.
 We sought to determine the feasibility of the
  WSB program in one of the poorest
  neighborhoods in Albuquerque, NM as a strategy
  to prevent obesity in Hispanic elementary school
           Experimental Design
    10 parents and 28 children were recruited to 2 WSBs

Participants met with school-based health provider before and
      after WSB program to discuss prevention of obesity

                Pre- and Post- WSB measures:
     (1) Height and weight for BMI percentile
     (2) Survey questions taken from CDC’s YRBS on
       fruit and vegetable intake, TV viewing and
       physical activity
     (3) 24 hour diet recall

  9 parents and 25 children completed the WSB program

 The WSB program was feasible with promising
  self-reported obesity reduction behavior
  changes (physical activity, fruit and vegetable
  intake) and no excessive weight gain in the
 group of children.
             Future Directions
 This feasibility WSB trial with health themes
  promoted by primary care clinicians through a
  school-based health clinic should be evaluated
  further as a potential community-based
  childhood obesity prevention strategy.
 Further investigation of the WSB should include
  a control group, larger sample size and longer
  trial length to look at obesity prevention and
  behavior changes for obesity risk reduction.
